Rob, 25, said keeping a lid on things with Kristen, 21, is not only important for his sanity, but also his career, the Edinburgh Evening News reports.

“Most actors encourage the attention because they think it will make them have a more lasting career, but I don’t think that’s the case,” he says. “The more of yourself you reveal, the less interesting people find you. Mystery lasts a lot longer.”

What do YOU think, HollywoodLifers — is Rob smart to keep his private life under wraps?
